Republicans will have to find 25 votes to bring back the school finance proposal that was filibustered last night; and the search for the six needed Democrats is proving difficult.

If the reaction from Democratic sources and social media is any indication, Sen. Wendy Davis’ filibuster last night has encapsulated Democratic frustrations over the massive budget cuts coming to social programs and education; making it more difficult for Senate Democrats to vote against their colleague.

Democratic sources say that the GOP’s bid for six votes seems to hang on Sen. Leticia Van De Putte and Sen. John Whitmire.

They discounted the possibility of Whitmire voting with the GOP because his new district is more liberal than his old one and now includes the very politically active Montrose neighborhood.

Still, Republicans are turning up the Senate on the Senate’s minority party. Conservative activist Michael Quinn Sullivan tweeted this morning that Gov. Rick Perry has threatened to veto the Senate redistricting map if Senate Democrats didn’t move to back the school finance proposal.

Senate sources confirm that the threat has been made and one said “it’ll only make our case to the Justice Department stronger.”

Gov. Perry had said that a special session could begin as soon as Tuesday (tomorrow) unless the House and Senate pass bills key to making the budget balance. Davis’ filibuster killed (probably) SB1811 in the Senate, while a long and raucous debate over banning text messaging while driving delayed consideration of HB6, SB8, and SB23 in the Senate.

Republican Sen. Robert Duncan, who is leading the effort to round up the needed Democratic votes, said that the Senate deal on education was as good as it get considering there aren’t the votes to raise taxes or spend more money from the Rainy Day Fund.

“The failure on the part of the Senate is not necessarily in the best interest of those who would object,” Duncan said. “There’s not going to be any achieved improvements.”
